STEAIVH JOENT FOR ROTARY CYLBNDERS.

SPECIFICATION forming part of Letters Patent No. 599,403, dated February 22, 1898.

Application filed May 15, 1897. Serial No. 636,665, (No model.)

To ctZZ whom it may concern:

Be it known that I, MICHAEL J. ROAOH, of Anderson, Madison county, Indiana, have invented certain new and useful Improvements in Steam-Joints for Rotary Cylinders,of which the following is a specification.

This invention pertains to improvements in steanrjoints for that class of rotary cylinders employed as paper-machine driers, &c. and the improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of an end portion of a rotary cylinder having asteam c011- neotion embodying my present improvements; Fig. 2, a similar side elevation of the steam connection upon an enlarged scale, and Fig. 3 a vertical diametrical section of the same.

In the drawings, 1 indicates the end of a rotary cylinderas, for instance, a paper-niachine drier; 2, the neck thereof, having the usual axial passage -way through it; 3, a flange bolted steam-tight against the end of the neck; 4, a pipe screwed into flange 3 and projecting outwardly therefrom, its exterior being truly cylindrical and concentric with the axis of neck 2, the direction of spirality of the thread where pipe 4 engages flange 3 being such that it will not tend to unscrew as the neck turns while resistance is offered to the rotation of the pipe; 5, a segment of a sphere formed upon the outer end of pipe. 4, its convex surface being toward flange 3; 6, a flanged cup fitting the convex surface of sphere-segment 5 steam-tight, the sphere-segment, however, being capable of rotation within the cup, the cup having a hub projecting toward flange 3, but fitting the pipe so loosely that the cup is capable of some degree of articulate motion with reference to the pipe; 7, a flanged hollow boss disposed against the flange of cup 6 and bolted steamtight thereto and projecting outwardly therefrom; 8, the steam-inlet pipe, screwed upwardly into the bottom of boss 7 and communicating through pipe 4 with the axial passage in neck 2 and consequently with the interior of the drying-cylinder; 9, an outward projection from boss 7, having, preferably, a downward turn to form an elbow; 10, the outlet-pipe for steam or the water of condensation, the same being screwed into projection 9, which projection has a passage through it in inward prolongation of pipe 10; 11, a washer seated against the inner end of the hub of cup 6 and loosely surrounding pipe 4 and perforated for the passage of oil; 12, an inwardly-cupped washer with its outer face engaging against the inner face of washer 11, this washer also loosely surrounding pipe 4; 13, a spiral spring surrounding pipe 4 and having its outer end abutting within the cup on the inner face of washer 12; 14, a ring loose upon pipe 4 and having its outer face cupped to receive the inner end of spring 13, the inner face of this ring 14 being formed with facial ratchets; 15, a second ring loose upon pipe 4 between ring 14 and flange 3, the outer face of this ring having a facial ratchet intermembering with the ratchet of ring 14; 16, the ratchets just referred to at the inner engagement of rings 14 and 15; 17, set-screws in rings 14, by means of which those rings can be secured against movement on pipe 4; 18, an oiler in the upper portion of cup 6 over sphere'segment 5, and 19 the usual siphonpipe, which extends from the interior of the drying-cylinder outwardly through the neck of the cylinder, this pipe in the present case having its outer end screwed through bridge 21 and into the passage of projection 9, so as to form practically an inward continuation of pipe 10.

Steam enters pipe 8 and goes through pipe 4 and the neck of the drier to the interior of the drier. Steam or the water of condensation passes outwardly through siphon-pipe 19 and through outlet-pipe 10. Pipes 8, 10, and 19 and boss 7 and cup 6, with the parts fixedly connected with them, are stationary, all the other parts revolving with the drier. As the drier revolves the ball-segment 5 turns within cup 6, the spherical character of the engagement between the sphere-segment and the cup providing for reasonable variations in the position of the stationary parts with reference to the revolving drier. The spring presses the cup steam-tight against the surface of sphere-segment 5, the oiler 18 being stationary and lubricating the rubbing surfaces, and also, in addition to oil-hole 20, lubricating the surface of washer 11, which washer is at liberty to turn with washer 12 .or to remain stationary with cup 6. Washer 11 may fit pipe 4 as snugly as is consistent with its turning thereon, while the hub of cup 6 is to be loose enough on the pipe, as before stated, to permit of articulation of the stationary parts with reference to the rotary parts. The hub of cup 6 may therefore partake of radial rubbing motion on the outer face of washer 11, while Washer 11 partakes of circular rubbing motion against washer 12. The tension of spring 13 may be adjusted by loosening the set-screw in ring 14 and turning that ring, the ratchets serving to move the outer face of ring 14 farther outwardly. After the tension of the spring has been properly adjusted then the set-screw in collar 14 is to be again tightened to hold the collar fast upon pipe 4. The same adjustment may be effected by loosening both set-screws 17 and turning collar 15. In the drawings collar 15 is shown as abutting against flange 3, under which conditions the office of the set-screw in ring 15 is simply to prevent rotation of the ring upon the pipe; butif the adjustment of the spring requires it ring 15 may be moved and fastened farther outwardly upon pipe 4 and entirely away from flange 3.

I claim .as my invention- 1. In a steam-joint for rotary cylinders, the combination, substantially as set forth, with the neckof the cylinder, .of apipe projecting axially and rigidly therefrom, a sphere-segment carried by the outer end of said pipeand presenting its convexity toward said neck, a cup engaging the sphere-segment, a boss secured to the outer portion of said cup and adapted to receive a pipe connection, a washer encircling said projected pipe at the inner hub of said cup, and a spring encircling said projecting pipe and acting between said Washer and an abutment secured to said pipe.

2. In a steam-joint for rotary cylinders, the

combination, substantially as set forth, with the neck of the cylinder, of a pipe projecting axially and rigidly therefrom, a sphere-segment carried by the outer end of said pipeand presenting its convexity toward said neck, a cup engaging the sphere-segment, a boss secured to the outer portion of said cup and adapted to receive a pipe connection, a washer encircling said pipeand engaging against the inner hub of said cup, a Washer encircling said pipe and engaging against the inner face of the first-mentioned Washer, and a spring engaging said pipe and engaging between said last-mentioned washer and an abutment carried by said pipe.

3. In a steam-joint for rotary cylinders, the

combination, substantially as set forth, with the neck of the cylinder, of a pipe projecting axially and rigidly therefrom, a sphere-segment carried by the outer end of said pipe and face, and an abutment carried by said pipe and having a facial ratchet engaging the ratchet of said ring.
